I know it's difficult to say but I whacked the top of my foot really hard against something earlier and it really hurt but I was able to walk fine, just felt a tad uncomfortable later.
Several hours later, now I've sat down and got back up again it's hurting to walk on it and I'm limping. No bruising or anything.
I also tripped over on the train platform and walked into my wardrobe. Today is not my day.
